  • Patent number: 6188177
    Abstract: A control system for controlling the illumination intensity of a gas discharge lamp to provide only necessary illumination and thus conserve power consumption. The control system has a daylight harvester which produces a control signal related to the available light within a given area. The control signal is conducted to a voltage controlled oscillator which, in turn conducts an oscillating signal to a frequency controlled ballast transformer that effectively drives the gas discharge lamp controlling the illumination intensity and energy consumption. The control system alternatively comprises a remote signal receiver for use alone or in addition to the daylight harvester. The control system with a remote signal receiver is controllable using a remote signal generator such as laser pointer. The remote signal receiver allows the user to control the illumination intensity of a gas discharge lamp from the area being illuminated.
